Introduction
Overview
Microgeneration systems such as Solar PV and small wind turbines are at their most efficient when the generated energy is
consumed on-site rather than exporting it to the grid. This is what we call 'self-consumption'.
eddi
is an energy management system for use with grid-tied PV or wind turbine systems. Excess energy from the
microgenertation system is used to heat water or rooms rather than exporting it to the grid.
A grid current sensor (supplied) simply clips around the incoming supply cable. This sensor is used to monitor excess power
and
eddi
automatically adjusts the voltage to the heater load, thereby consuming the surplus power. A self-powered
wireless sensor (
harvi
) is available separately.
An internal expansion interface provides a means to install a Relay & Sensor Board to enable various functions such as auto
switching from day-time and night-time supply, heat pump interfacing for Legionella control and temperature sensing.
